Application filed. December Tdalliwhom it may concern: I

Be it known that I, HAROLD GQNILso a citizen ;of the United States v of America, residing at Detroit, in the countyof'Wa-yne and State of Michigan, "have invented certain new and useful,Improveinentsin Loading- Attachments for Trucks, of which the =following" is a specification, reference being had therein to the accompanying drawings. The inventionfrelates to loading attachments particularlydesigned for use upon motor trucks and'other vehicles of transportation and the invention consists in various features of construction as hereinafter set forth. l I i I In the drawings I r 1 e e Figure 1 is a sectional'side elevation of a truck to which my improvement is applied; a Figure 2 is a plan view thereof; 7 a

Thisas showncomprises the hydraulic hoist '-C,, carrying'the oss head D with shives E'thereon and with cables F anchorfed to' the frame at Gpass ng over the shivesE and attaching to the arms 'H, which lift" and dump the body.

'throughbearings in the arms K and one of which, 1s attached to a sprocket wiheel'R.

This sprocket wheel is, connected by v sprocket chaln S with a sprocket T uponthe shaft L. U is an arm projecting radially fromthe sprocket T and attached to a rod,

U-, the end of whichengages a locking" bolt V, The rod U is also formedwith a rack portion U which engages a pinion 'l/V at .tached to v a ratchet wheel fl/Vfwhile a ratchet lever VV is arranged for operating 7 the ratchet wheel to revolve the pinion and to move the rack.

To dumpthe load the .IOd X is operated so that thecani X will liftthe latchV and permit the "{movementbf the. r'odU, rock arm U and sprocket T. Such movement is efiected' either by the load in'the'scoop being unbalanced with atendency'jto dump the scoop, or "by means ofthe' lug Y on the*arm* K which, in the swinging of said arms, comes into contact with the arm U and actuates the same. 'fThus, byturning the sprocket T, will "actuate the chain' "Sand sprocket wheel-'R,

scoop as a scraper. This may be accomplished by first releasing the bolt V and then operating the ratchet lever W to turn the ratchet wheel W and pinion WV, which latter actuates the rack U on the. rod U, turning the arm U, sprocket T, chain S and sprocket wheel R and vthereby revolving the scoop into a vertical'position. The parts are locked in this position by the re-engagement of the bolt V with the rack teeth of the rod U, which will hold the scoop from turning, while it is used at. a scraper or for other uses.

To facilitate the loading of barrels or similar articles into the wagon, the end gate of the body B, which is hinged at its lower end at B may be turned down so that its outer edge will rest in the scoop J when the arms K are raised into an in clined position. Thus articles, such as barrels, which are lifted by the scoop, will be automatically rolled down the end gate into the body of the vehicle.

The construction as described is one which may be readily attached to almost any standard construction of truck and can be operated by means already provided on the truck, such as the hydraulic hoist, which has However, it is not essential to my invention that the mechanism should be operated by a hydraulic hoist, as any mechanism driven by the motor may be employed for furnishing the necessary lift-- ing power.

What I claim as my invention is:

1. A loading device for vehicles comprising a scoop, swinging arms attached to the vehicle body upon which said scoop is mounted, means for lifting said arms to swing the scoop over the body, means for preventing the scoop from turning during the swinging movement, and releasing means for permitting the'turning of the Scoop to dump the load when above the body.

2. A loading device for vehicles comprising a scoop, swinging arms attached to the vehicle body on which said scoop is mounted, means for lifting said arms, means for preventing the turning of the scoop during transit consisting of a sprocket attached to the scoop, a sprocket concentric with the pivot of said swinging arms, a sprocket chain connectin said sprockets, means for normally holdmgthe second-mentioned sprocket from turning during the swinging of said arms, and releasing means to permit the turning of said sprocket when the load is to be dumped.

A loading device for vehicles comprising a scoop, arms on which said scoop is mounted pivotally attached tothe body of the vehicle, means for swinging said arms upward to carry the scoop above the body, means for holding the scoop from turning during the upward movement thereof comprising asprocket attached to the scoop, a sprocket concentric with the pivot of said arms, a sprocket chain connecting said sprockets,.a radial arm extending from the second sprocket, a rod connected to said arm and extending longitudinally of the vehicle, a locking bolt for holding said rod from movement, and means for releasing said bolt to permit the movement of said rod and the dumping of the load from the scoop.

4. A loading device for vehicles comprising a scoop, arms on which said scoop is mounted pivotally attached to the body of the vehicle, means for swinging said arms upward to carry the scoop above thebody, means for holding the scoop from turning during the upward movement thereof comprising a sprocket attachedto the scoop, a sprocket concentric with the pivot of said arms, a sprocket chain connecting said sprocket-s, a radial arm extending from the second sprocket,a rod connected to said arm and extending longitudinally of the vehicle, a locking bolt for holding said rod from movement, means for releasing said bolt to permit the movement ofsaid rod andthe dumping of the load from the scoop, a rack on said rod, a pinion engaging said rack, a ratchet wheel secured to said pinion, and a ratchet lever engaging said wheel to operate said pinion and rack in restoring the parts rest upon the scoop and form a runway therefrom to the body.

6. A loading device for vehicles comprising a scoop, swinging arms attached to. the vehicle body on which said scoop ism ounted, means forlifting said arms,'means for preventing the turning of the scoop during transit consisting of a rotatable member attached to the scoop, a rotatable member concentric with the pivot of said swinging arms, a member connecting said rotatable members, means for normally holding the" second mentioned rotatable member'from turning during the swinging of said arms, and releasing means to'permit the turning of said rotatable member when the load is. to be dumped. v i I 7. The combination with a vehicle, of a ground engaging scoop adapted to discharge material into the body of said-vehicle, means for actuating said scoop, said 'scoop being, adjustable to a position to serve as a scraper, and adjustable means independent of said actuating means for retaining said scoop in said position.

8. The combination with avehicle having a frame, of a dumping body mounted on said frame, dumping mechanism for said body including a flexible member connected flexible member connected to said armsand adapted to be connected to the flexible mem- 10;"

ber aforesaid when the same is. detached from said frame whereby said scoop and arms may be actuated insteadof said body. In testimony whereof I aflix' my signature.
